Step-by-step explanation:

Note that (0,0) and (3,1) are points on the ramp.

slope of ramp = (1-0)/(3-0) = ⅓

equation of ramp: y = ⅓x

If the base of triangle is extended to 9 ft, the height of the ramp will be ⅓·9 = 3 ft

Answer:

[tex]\lambda = 3[/tex]

Step-by-step explanation:

Given

[tex]v = 30m/s[/tex]

[tex]f = 10\ Hz[/tex]

Required

Determine the wavelength [tex]\lambda[/tex]

This is calculated as:

[tex]\lambda = \frac{v}{f}[/tex]

Substitute values for v and f

[tex]\lambda = \frac{30}{10}[/tex]

[tex]\lambda = 3[/tex]

Hence, the wavelength is 3

Answer:

Step-by-step explanation:

1/6 + 1/9 = 3/18 + 2/18 = 5/18

5/18 of the punch is either pineapple or orange.

The fraction that represents pineapple juice or Orange juice is 11/30

A common fraction is a numeral that represents a rational number. A fraction is a part of a whole.

Given here pineapple juice is  1/6 of a fruit punch and orange juice is  1/9 of the punch. Let the whole punch is equal to x then  

pineapple juice =( 1/6) × x and Orange juice = (1/9 )× x

Hence the total of the pineapple juice and orange juice is                    ( =1/6) × x + (1/9 ) × x

=11x/30

Now this total expressed as part of the whole is 11x/30 / x = 11/30

Hence, the final answer is equal to 11/30

80 - 12 = 68 (Price after the sale)

Answer:

[tex]\frac{9}{11}[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have:

3 red cards

6 blue cards

2 green cards.

What is the probability that the card is not green?

3 + 6 + 2 = 11 cards, of which 3 + 6 = 9 are not green. So

[tex]\frac{9}{11}[/tex] probability that the card is not green

[tex]a = 8[/tex] and [tex]b = 2[/tex]

Step-by-step explanation:

Given

[tex]\sqrt[3]{x^{10}}[/tex]

[tex]x = -2[/tex]

Required

Express as: [tex]a\sqrt[3]{b}[/tex]

Substitute -2 for x in [tex]\sqrt[3]{x^{10}}[/tex]

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{(-2)^{10}}[/tex]

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{1024}[/tex]

Express 1024 as 2^10

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{2^{10}}[/tex]

Apply law of indices:

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{2^{9+1}}[/tex]

Apply law of indices: Split

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{2^{9}*2^1}}[/tex]

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{2^{9}} *\sqrt[3]{2^1}}[/tex]

[tex]\sqrt[3]{x^{10}} = \sqrt[3]{2^{9}} *\sqrt[3]{2}}[/tex]

[tex]\sqrt[3]{x^{10}} = 2^{9*\frac{1}{3}}} *\sqrt[3]{2}}[/tex]

[tex]\sqrt[3]{x^{10}} = 2^3 *\sqrt[3]{2}}[/tex]

[tex]\sqrt[3]{x^{10}} = 8\sqrt[3]{2}}[/tex]

Using probability concepts, it is found that:

a) 0.43 = 43% probability that the patient experiences neither depression nor weight gain.

b) 0.3929 = 39.29% probability that the patient experiences depression given that the patient experiences weight gain.

c) 0.275 = 27.5% probability that the patient experiences weight gain given that the patient experiences depression.

d) No.

e) No.

---------------------

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]  

----------------------

Item a:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.4 + 0.28 - 0.11 = 0.57[/tex]

[tex]p = 1 - P(A \cup B) = 1 - 0.57 = 0.43[/tex]

0.43 = 43% probability that the patient experiences neither depression nor weight gain.

Item b:

[tex]P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{0.11}{0.28} = 0.3929[/tex]

0.3929 = 39.29% probability that the patient experiences depression given that the patient experiences weight gain.

Item c:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.11}{0.4} = 0.275[/tex]

0.275 = 27.5% probability that the patient experiences weight gain given that the patient experiences depression.

Item d:

[tex]P(A \cap B) \neq 0[/tex], thus, the events are not mutually exclusive.

Answer:

option #1 is a reflection over the x-axis.

Step-by-step explanation:

option #1 is a reflection over the horizontal axis, which is the x-axis. the end of the bold horizontal line in the middle of the graph (the one that goes from side to side) is labeled with an "x" which indicates that it's the x-axis.

option #2 is a reflection over the vertical axis, which is the y-axis. the top of the bold vertical line in the middle of the graph (the one that goes up and down) is labeled with a "y" which indicates that it's the y-axis.

option #3 is not a reflection over either of the axes. it actually seems to be a rotation rather than a reflection.
